ALL CAPS

Methods

Methods are a special kind of functions, they are functions called from another value.

So that's what the . in console.log is for, we call the function log from the console, so it will run its actions using the console.

Now every value types have methods in JS, for example, numbers have a special toFixed method that allows you to specify how many decimals you want when you convert them to string:

let thirdOf10 = 10 / 3
console.log(thirdOf10) // -> 3.3333333333333335 that's a lot of precision...
console.log(thirdOf10.toFixed(3)) // -> '3.333' that's quite enough !
console.log(thirdOf10.toFixed()) // -> with no argument, we get just '3'

So here in that second to last line we call toFixed from the value of the variable thirdOf10, with the argument 3, saying that we want 3 decimal numbers in our string conversion.

Since they are functions, they can also return values.

Instructions

One of the value with the most methods are strings, you can do a lot of things with them.

For this exercise you will have to use the methods toUpperCase and toLowerCase from the provided variable message.

• Create a noCaps variable of the value of message but in lower case.
• Create an allCaps variable of the value of message but in upper case.

Just remember ALL CAPS when you spell the man name
